.net - C++/CLI use of Action<...,...> and Func<...> unsupported? -


It does not appear that C ++ / CLI has support for Action and Funk representatives in the system namespace. Not for at least one of the more common arguments: 

  System :: Action & lt; Int, int & gt; ^ ^ Action = nullptr; System :: Fun & lt; Int, int & gt; ^ Func = nullptr; Results in both errors:  
  Error C2977: 'System :: Action': Very common logic error C2955: 'System :: Action' Common logic list is required for the use of general category  
 
 Single logic function only: 
 
  System :: Action & lt; Int & gt; ^ ^ Action = nullptr;  
 
 Anyone knows, why or what is missing to do this work. I am using Visual Studio 2008 and the target framework is 3.5 in this project.

Action based on the framework version you are using and < Code> Func types are different.

In 3.5 framework, there are all definitions in Func (not normal or normal) System.Core.dll. It is also true for versions of verb with 2 or more common parameters action and action < T1, T2 & gt; Although there are mscorlib in.

4.0 Definition includes all the definitions of Func and action mscorlib in the system that contains type forwarders. The core which now points back to the MScLibb.

The Silverlight 4.0 3.5 framework is close to the resolution.

Ensure that you have a reference to the appropriate DLL for your solution.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
